Description

The invention relates to a prefabricated device for a tank truck specified in the restrictive part of claim 1 of the claims. In addition, the invention relates to a tank truck having such an assembly device.

US 8,997,307 B2 shows a collecting device for a tank truck, which has a blade tapering in the longitudinal direction of the collecting device for raking liquid manure located on the ground. In addition, the collection device includes a suction inlet for suction of liquid manure, which is collected through the dump. Further, the prefabricated device also has an interface whereby the suction inlet can at least indirectly connect to the tank car tank.

Such prefabricated devices can, for example, be mounted on a tank truck, which are used in agriculture for spreading liquid manure or slurry in fields or meadows. Such tankers have a tank for placing liquid manure or slurry. In addition, such a tanker truck may have a pumping device, the drive of which can be carried out, for example, by means of a power take-off shaft of a traction or carrier vehicle. In tanks for liquid manure, respectively, tank trucks, made in the form of trailers, there is also the possibility of driving the trailer axle, which serves as the driving axle, through the so-called synchronous tractor power take-off shaft.

When using the collection device described above, that is, with the prescribed mounting position of the collection device on an appropriate tanker truck and using the collection device for collecting and sucking liquid manure, a significant problem is that by using the suction inlet of the collection device, it is possible to reliably suck in the liquid manure healed by dump, and on the other hand, it is especially compact and reliable to place the assembly device on the tank truck when not in use.

Therefore, it is an object of the present invention to provide an assembly device for a tank truck by which these named problems are solved in a particularly simple manner.

This problem is solved using a prefabricated device for a tank truck with the features of an independent claim. Preferred embodiments containing expedient and non-trivial improvements of the invention are indicated in the dependent claims.

The assembly device for a tank truck proposed by the invention includes a blade (retractable flap), tapering along the longitudinal direction of the collection device, for raking liquid manure located on the ground. In addition, the collection device according to the invention has a suction inlet for sucking up liquid manure that is collected by means of a dump, as well as a mating point whereby the suction inlet can at least indirectly be connected to the tank car tank. The assembly device of the invention is characterized in that the assembly device includes a height adjustment device, by means of which the height position of the suction inlet relative to the blade can be rearranged.

The suction inlet is preferably located where the blade in the transverse direction of the collecting device is the narrowest. This gives the advantage that liquid manure in this place of the dump, respectively, in the area of the narrowest place of the dump is usually heaped to the highest height when the dump moves on the ground by means of a tanker truck. The suction inlet may, for example, be a pipe, which, through the interface, can at least indirectly connect to the opening of the tank truck. This interface may, for example, be a flange connection to which a suction inlet can be attached. In addition, on such a flange connection, for example, another pipe or hose can be additionally installed, which can serve as a connecting element between the suction inlet and the interface located on the side of the tank, for example, also in the form of a flange connection or the like. Further, the prefabricated device or tank truck itself can have a pump, through which a reduced pressure can be created to suck in the slurry slurry, due to which, by means of the suction inlet, slurry slurried by the blade can be moved, respectively, to be sucked into the tank.

An essential aspect of the invention relates to the possibility of rearranging the relative height of the suction inlet with respect to the blade. Moreover, the invention is based on the fact that it is discovered that, depending on how quickly the blade moves over a particular soil, liquid manure is heaped into the dump area at various heights. Further, the heaving height of the liquid manure in the dump area may also depend on the viscosity of the liquid manure. In order to collect the liquid manure located on the ground especially well and, first of all, also to dig into the dump area, it will actually be advisable to move the dump especially close to or on the ground lying on it. Depending on how high the liquid manure can be slaughtered by the blade, typically the distance between the liquid manure to be dumped into the blade area and the suction inlet will be different. It is this distance that is the purpose of the assembly device proposed by the invention, while the height position of the suction descent relative to the blade is movable.

By means of the assembly device of the invention, regardless of the position of the blade, the suction inlet can be rearranged relative to the blade in the vertical direction, so that the distance between the soil and the suction device and the distance between the soil and the blade can be set independently of one another at least in some ranges. For example, a blade can lower so that it lays on the ground. Depending on how high the liquid manure is plowed through the blade, that is, depending on how far the surface of the liquid slurry being removed is from the suction inlet, the suction inlet can be rearranged in height with respect to the surface of the liquid slurry being dispensed, and regardless of the height setting dump. Due to this, the suction inlet in the vertical direction of the collecting device and also also in the vertical direction of the tanker truck, since the collecting device is mounted on a tanker truck, can be installed in the most optimal way possible, so that liquid manure that is demolished in one place and which is heated by a dump can .

One of the preferred embodiments of the invention provides that the device for shifting the height is designed so that, depending on the reduced pressure in the tank car, made in the form of a vacuum tank, automatically rearrange the position along the height of the suction inlet relative to the blade. Preferably, the collection device includes a sensor, in particular in the area of the interface, which is designed to measure the reduced pressure in the vacuum tank and to transmit the corresponding measurement data to the height adjustment device. In the case of a vacuum tank using a vacuum pump, for example, in the form of a vane pump, the vacuum tank of a tank truck is placed under vacuum during the filling process, more precisely, actually under reduced pressure, due to which liquid manure is sucked into the vacuum tank through the suction inlet. Depending on how viscous the suction liquid manure is, completely different reduced pressures may be required in order to reliably and, above all, also quickly move the liquid manure into the vacuum tank. Due to the fact that the height shifter is designed to automatically change the position along the height of the suction inlet relative to the blade, depending on the reduced pressure in the vacuum tank, the best possible suction performance can always be guaranteed. For example, the reduced pressure achieved in a vacuum tank may depend on the current filling level of the vacuum tank. In addition, the reduced pressure generated in the vacuum tank can, of course, also depend on the vacuum pump used. In principle, it is possible for the reduced pressure in the vacuum tank to fluctuate during the filling process. In this case, by means of a device for changing the height, it is possible to lower or raise the suction inlet, if necessary, depending on how large the current measured reduced pressure in the vacuum tank is. As an adjustable value, for example, a certain flow rate through the suction inlet can be set, in order to achieve this predetermined adjustable value and depending on the measured reduced pressure in the vacuum tank, the height position of the suction inlet relative to the blade can be automatically adjusted. Further, alternatively or additionally, it is also possible that the viscosity of the liquid manure is determined by means of an appropriately measuring device of the collecting device, and depending on the measured viscosity of the liquid manure, the height position of the suction inlet relative to the blade can also be automatically rearranged. In this way, the duct through the suction inlet can be optimized, and at the same time also filling the tank of said tanker.

According to another preferred embodiment of the invention, it is provided that the height adjusting device is designed to automatically rearrange depending on the level of liquid manure being pumped through the dump and / or depending on the distance between the surface of the liquid manure being pumped through the dump and the suction inlet height position of the suction inlet relative to the blade. Preferably, the collection device itself has a measuring device for this purpose, which is designed to measure the level of liquid manure and / or the distance between the surface of the liquid manure and the suction inlet and to transmit the corresponding measurement data to the height adjusting device. As already mentioned above, the level of liquid manure, respectively, the distance between the surface of the liquid manure being pumped through the blade and the suction inlet are essential parameters that affect the flow of liquid manure through the suction inlet. The higher the liquid manure level in the dump area, the farther the suction inlet can rise relative to the dump. In addition, the height position of the suction inlet relative to the blade can be set so that the distance between the surface of the slurry being dug and the suction inlet is minimized, or if the level of slurry is high enough, the suction inlet is also immersed in the slurry being slaughtered. Due to the fact that the level of liquid manure and / or the distance between the surface of the slurry of manure and the suction inlet is recorded and can be taken into account when controlling the device for changing the height, the flow through the suction device can be optimized.

In another preferred embodiment of the invention, it is provided that a balancer is mounted on the suction inlet, which is located on the blade with the possibility of rotation around an axis extending in the transverse direction of the collecting device, while the height adjustment device has a hydraulic cylinder by which the balancer can rotate around the axis relation to the dump. This allows a particularly simple and stable permutation to change the position of the height of the suction inlet relative to the blade. Said hydraulic cylinder of the height adjusting device preferably relies on the rear end of the blade and can push the balancer, which is mounted on the suction inlet, in the direction of the height of the collecting device from the blade or attract it, depending on whether the suction inlet is rearranged or way down.

According to another preferred embodiment of the invention, it is provided that the blade in the prescribed mounting position of the collecting device for shifting the height of the blade has the ability to move relative to the tank truck between the lowered operating position and the raised transport position. If, for example, the assembly device in its position mounted on the tank truck is not currently needed, the blade can move to the raised transport position, in which the blade is not in contact with the ground on which the tank truck is currently traveling. In this way, unnecessary blade wear can be prevented. But as soon as it becomes necessary to collect and dig liquid manure located on the ground by means of a collecting device, the dump can be moved to the lowered working position.

Another preferred embodiment of the invention provides that the assembly device for adjusting the height of the blade includes at least one hydraulic cylinder and one traction means, while in the prescribed mounting position of the assembly the hydraulic cylinder is located on the tank truck and using the traction means at least indirectly connected to the blade. The traction means may, for example, be a belt or a chain. In either case, the advantage is that no compression forces are transmitted through the traction means to the hydraulic cylinder. Due to this, the hydraulic cylinder is loaded only in tension, but not in compression. That is, for example, if, due to uneven soil, the blade moves up, then this does not affect the hydraulic cylinder, since the traction means cannot transmit compressive forces to the hydraulic cylinder. Even if the dump due to uneven ground will be driven up, respectively, suddenly move up, this will not harm the hydraulic cylinder. Instead of a hydraulic cylinder, for example, a pneumatic cylinder or a servomotor may also be provided.

In another embodiment of the invention, it is provided that in the prescribed mounting position of the collecting device, the hydraulic cylinder is coaxial with the longitudinal direction of the tank truck, while the traction means is redirected (deflected) by substantially 90 degrees by the bypass roller of the collecting device located on the tank truck. An advantage in this preferred embodiment of the invention is that the hydraulic cylinder can also be provided with a very high stroke, and yet it can nevertheless be located on the tank truck especially compactly, since in the prescribed mounting position of the assembly the hydraulic cylinder is aligned with the longitudinal direction of the tank truck. With the help of a bypass roller, the traction means can be redirected essentially 90 degrees, so that when lifting the hydraulic cylinder in the longitudinal direction of the vehicle, the possibility of raising and lowering the blade in the vertical direction of the tank truck is made possible in a particularly simple way. But, depending on the installation situation on the tank truck, it is also possible to position the hydraulic cylinder with its axis not aligned with the longitudinal direction of the tank truck, but in a completely different orientation.

According to another preferred embodiment of the invention, in the prescribed mounting position of the collecting device, the blade has a degree of freedom of movement in the transverse direction of the tank truck. Due to this, the blade during use can shift to the left and right relative to the tanker truck. That is, the blade can be mounted on a tank truck in a freely oscillating manner, at least in some limits.

Another preferred embodiment of the invention provides that the collection device has at least one towing means attached to the blade, which can be mounted on a tank truck to pull the blade through a tank truck. This traction means may, for example, be a wire rope. Preferably, the towing means is of such length and can be mounted on a tank truck in such a way that when lifting and lowering the blade, it only hangs on the towing vehicle, which serves to raise and lower the blade.

In another preferred embodiment of the invention, it is provided that at least one support element is located on the blade, whereby the blade in the raised transport position can rest on the tank truck from below. The support element can also be understood as a kind of emphasis, so that the blade in the raised transport position, the raised transport position by means of the support element abuts against the tank truck from the lower side. Due to this, you can do without laborious positional regulation, respectively, positional control for the location of the blade in the raised transport position, the raised transport position. For example, it is possible for the blade to be brought into an elevated transport position purely with force control, and automatically, as soon as the support element is supported by the tank truck, a certain threshold value of force will always be reached, since the blade cannot go any further. This greatly facilitates the movement of the rearrangement of the blade in the transport position, since it does not require any laborious adjustment, respectively, control.

Another preferred embodiment of the invention provides that the blade has a left and right section, which, to swivel the width of the blade between the extended working position and the folded transport position, can be rotated against the rest, in particular the substantially V-shaped part of the blade. The sections of the blade, with the ability to turn outward and inward, form the front side of the blade, and the rest in the prescribed direction of movement of the blade forward of the blade forms the rear part of the blade. In other words, the blade in the forward direction in the prescribed mounting position extends from front to back, converging conically. Due to the fact that the left and right sections have the ability to rotate between the extended working position and the folded transport position, a particularly large working width of the blade can be set if necessary, and when not used, the blade can be folded up especially compactly. In particular, the left and right sections can be folded to such an extent that both sections do not protrude from the tanker in the transverse direction of the vehicle.

Preferably, the plow width swap assembly has corresponding hydraulic cylinders whereby the left section and the right section are at least indirectly connected to the rest of the blade. In this case, it can also be provided that both the rearrangement of the blade width and the rearrangement of the blade height are related to each other in such a way that, with regard to the rearrangement of the height and also the rearrangement of the blade width, the indicated operating positions and transport positions can be automatically adopted. For this, the operator of the prefabricated device must, for example, use only one single actuating element, such as, for example, a switch or the like, in order to bring the blade to its working position, respectively, to the transport position in height and also in width.

The tanker of the invention includes a prefabricated device of the invention or one of the preferred embodiments of the device of the invention.

In the figures, the same or functionally identical elements are provided with the same reference signs.

A tank truck 10 having a tank 12 serving as a slurry tank is shown in FIG. 1 in side view. Under the tanker truck 10, a collecting device 14 is installed, which serves to collect, dig, and suck up liquid manure. The collection device 14 is installed behind the drawbar 16 and under the tank 12. The collection device 14 includes a tapering blade 18 in the longitudinal direction x of the collection device 14 for dumping liquid manure located on a soil not shown separately. In this image, the blade 18 is located in its elevated transport position, in which the blade 18 does not touch the ground.

The blade 18 on its lower side may, for example, have runners and / or rollers on which the blade 18 can slide and / or roll on the ground. Further, a plastic or rubber scraper may also alternatively or additionally be located on the underside of the blade 18 by means of which liquid manure can be especially scraped off the ground.

In the prescribed mounting position of the collecting device 14 shown here, the longitudinal direction x, the transverse direction y and the vertical direction z of the collection device correspond to the longitudinal direction x, the transverse direction y and the vertical direction z of the tank truck 12. That is, when it comes to the longitudinal direction x, the transverse direction y or the vertical direction z, these directional data should be understood synonymously for both the tanker truck 12 and the prefabricated device 14.

The collection device 14 also includes a suction inlet 20 for suctioning liquid manure, which is pumped through the blade 18. The suction inlet 20 is made in the form of a pipe bent essentially in the form of a quarter circle. In addition, the collection device 14 also has an interface 22, through which the suction inlet 20 can indirectly connect to the tank 12 of the tank truck 10. Through the interface 22, the intake inlet 20 is connected to a flexible hose 24, which, in turn, is connected to a separately designated the opening of the tank 12. On the inside of the tank 12 is also installed obliquely pipe 26, through which the liquid manure that is sucked in by means of the suction inlet 20 is moved inside the tank 12.

There is also a screw conveyor 28 inside the transparent tank 12 shown in this case, through which the liquid manure placed in the tank 12 can be transported to the outlet of the tank 12 not indicated separately, when the liquid manure must be moved from the tank 12. But instead of the screw conveyor 28 inside the tank 12 can also be located other means of movement for moving outward liquid manure placed in the tank 12.

In figure 2, the tanker truck 10 is shown in a plan view, while the blade 18 is still in its raised transport position. The blade 18 includes a right section 30 and a left section 32, which, for rearranging the width of the entire blade 18 between the extended working position and the folded transport position shown here, are supported to rotate on the remaining substantially V-shaped portion 34 of the blade 18. That is, with by means of these rotatable sections 30, 32, the width of the blade 34 can be varied according to need. When the blade 18 is in the raised transport position, it can also be brought into the folded transport position shown here, so that both sections 30, 32 to the smallest possible extent or not protrude at the sides of the tank 12, respectively, the tank truck 10.

Figure 3 shows the tank truck 10 in front view, while the blade 18 is again located in its raised and folded on the sides of the transport position. In this image, you can once again clearly see that the blade 18 is located, being removed from the ground to such an extent that it does not touch it. Further, in this front view, you can clearly see that, thanks to the retracted sections 30, 32, the blade 18 also does not protrude beyond the tank truck 10 on the sides.

Figure 4 mounted on the tank truck 10, the collecting device 14 is shown in a slightly enlarged detailed side view, while the blade 18, in turn, is in its folded on the sides and shifted upward transport position. In this upper position of the transport position, the blade 18 with several support elements 36, 37 is supported from the bottom by a tank truck 10.

The assembly device 18 for shifting the height of the blade 18 includes hydraulic cylinders 38 mounted on the tank truck 10 on the left side and on the right side, which are located with its axis in the longitudinal direction x of the tank vehicle 10. For shifting the height of the blade 18, the assembly 14 includes themselves also the corresponding traction means 40, which are mounted on the respective hydraulic cylinders 38. Traction means 40 mounted on the tank truck 10 on the left side and on the right side redirect substantially 90 degrees by means of respective bypass rollers 42 of the assembly 14. At their longitudinal ends facing away from the hydraulic cylinders 38, the traction means 40 are at least indirectly secured to the blade 18. When the hydraulic cylinders 38 are retracted, the blade 18 can move into the raised conveyor shown here position. As soon as the supporting elements 36, 37 from the lower side come into contact with the tank truck 10, the raised transport position of the blade 18 is reached. Due to this, it is possible to do without a particularly time-consuming positional control of the hydraulic cylinders 38, instead, for example, disabling the movement of the hydraulic cylinders 38, which is regulated by force, can be provided.

For rearranging the width of the blade 18, that is, for folding and folding the two sections 30, 32, the collecting device 14 includes the corresponding hydraulic cylinders 44, through which the left section 32 and the right section 30 not visible here are at least indirectly connected to the rest of 34 blade 18. When retracting and extending the hydraulic cylinders 44, these two sections 30, 32 can expand and fold. It is possible that the hydraulic cylinders 38, 44 in their control are connected to each other so that the lift of the blade 18 to the transport position shown here also automatically causes the folding of both sections 30, 32 of the blade 18. And vice versa, it can also be provided that two hydraulic cylinders 38, 44 were connected to each other by control technology so that lowering the blade 18 caused both sections 30, 32 to unfold in their extended operating position. But with the same success, it is possible that the control of two hydraulic cylinders 38, 44 was carried out completely independently of each other.

In Fig. 5, the assembly device 14 is shown separately in a partially transparent side view, while the hydraulic cylinders 38, the traction means 40 and the bypass rollers 42 are not shown in this image used to rearrange the height of the blade 18. Along with the possibility of rearranging the height of the blade 18 relative to the tank truck 10, the collecting device 14 also makes it possible to rearrange the tubular suction inlet 20 relative to the blade 18 in height, that is, in the vertical direction z.

To realize this possibility of relative rearrangement of the height of the suction inlet 20 with respect to the blade 18 from the rear side, a balancer 46 is fixed on the suction inlet 20, which rests on the blade 18 with the possibility of rotation around the axis 48 extending in the transverse direction z of the collecting device 14. As you can see , the axis 48 is located at the rear end of the rest, respectively, of the rear 34 of the blade 18. The balancer 46 can be rotated around the axis 48 by means of a hydraulic cylinder 50, which is part of a separately designated Accessories for changing the height of the suction inlet 20.

When extending the hydraulic cylinder 50, the balancer 46 in accordance with this image rotates around the axis 48 in the clockwise direction, as a result of which the suction inlet 20 also rotates accordingly. In this case, the relative positioning of the suction inlet 20 with respect to the blade 18 is changed, while, among other things, the height position of the suction inlet 20 relative to the blade 18 is changed. When the hydraulic cylinder 50 is pulled in, vice versa, the balancer 46 can rotate around axis 48 against the direction clockwise, as a result of which the suction inlet 20 again moves closer, respectively, moves towards the blade 18 in the vertical direction z.

Due to the pivoting movement of the suction inlet 20 about the axis 48 when the hydraulic cylinder 50 is activated, the relative positioning of the suction inlet 20 in the longitudinal direction x relative to the blade 18. As a result, it is preferable that the flexible hose 24 not shown here be installed at the interface 20 so that with its help a certain compensation of length and height can be realized when the suction inlet 20 is displaced together with the mating point 22 relative to the blade 18 and together with those As a consequence, also relatively tsisternovoza 10.

In FIG. 6, the region A indicated in FIG. 5 is shown in an enlarged detailed view. Here again, the balancer 46 is clearly visible, which is secured from the rear side to the suction inlet 20 and is rotatable by a hydraulic cylinder 50, whereby the relative positioning of the suction inlet 20 with respect to the blade 18 in the longitudinal direction x and in the vertical direction z can be changed. Depending on the height to which liquid manure is being heaped in the area of the blade 18, the relative position of the height of the suction inlet 20 with respect to the blade 18 can be set according to need, so that at any time it can be guaranteed that the liquid manure heaped by the blade 18 in its back region can be absorbed through the suction inlet 20 in a reliable and most efficient manner possible.

Figure 7 shows a part of the precast device 14 in a plan view. At the same time, two sections 30, 32 are depicted both in their extended operating position and in their folded transport position, therefore, sections 30, 32, as well as the hydraulic cylinders 44 required for the relocation process, are depicted twice. In this image, it can be seen that the hydraulic cylinders 44 act on the respective extensions 52, located essentially at right angles to the two sections 30, 32 and fixed on them. This facilitates the rotation of the two sections 30, 32 by means of the hydraulic cylinders 44, since even with the sections 30, 32 fully extended, the outwardly extending outward sections, the hydraulic cylinders 44, thanks to the right-angled extensions 32, still have a lever arm.

The height adjustment device, not separately designated, which includes a hydraulic cylinder 50 so that the suction inlet 20 can be rearranged relative to the blade 18, includes a sensor 54, which is only indicated here schematically. The sensor 44 is designed to measure the reduced pressure in the tank 12 and to transmit the corresponding measurement data to a height adjustment device, which serves to relocate the suction device 20. The height adjustment device is designed to control the hydraulic cylinder 50 depending on the measured reduced pressure in the tank 12 and thus automatically rearrange the relative position along the height of the suction inlet 20 with respect to the blade 18. The lower the izhennoe pressure in the tank 12, the further lowers the suction inlet 20 with respect to the blade 18, and vice versa. Tank 12 may, for example, be a vacuum tank.

The relative rearrangement of the height of the suction inlet 20 can also be carried out automatically depending on the registered level of liquid manure being shipped through the blade 18 and / or depending on the distance between the surface of the liquid manure being shoved through the blade 18 and the suction inlet 20, more precisely , not separately designated, oriented in the direction of the soil by the opening of the suction inlet 20. For this, the collecting device 14 may have a measuring device, which is designed to in order to measure the level of liquid manure and / or the distance between the surface of the liquid manure and the suction inlet 20 and transmit the corresponding measurement data to a device for changing the height, which on their basis respectively controls the hydraulic cylinder 50.

On Fig-11 mounted on the tank truck 10, the collecting device 14 is again shown in the same views as in Figs. 1-4, wherein the blade 18 is located in its lowered and extended operating position. On Fig and 11 it can be clearly seen that the supporting elements 36, 37, due to the lowering of the blade 18 relative to the tank truck 10, are now removed from the bottom side of the tank truck 10 not indicated separately in the vertical direction z. Thanks to the flexible hose 24, this relative movement of the blade 18 with respect to the tank truck 10 can be easily compensated.

To limit the displacement of the blade 18 relative to the tank truck 10 in the longitudinal direction x of the vehicle, the collecting device 14 includes at least one traction means 56, which is mounted on the blade 18 and in the area of the drawbar 16 on the tank truck 10. Preferably, these two traction means are mounted on the right and to the left of the hose 24 in the area of the drawbar 16 and on the blade 18. After the blade 18, due to the extension of the hydraulic cylinders 38, has been completely lowered to the ground, when the tank truck 10 moves forward, the blade extends exclusively or at least mainly with traction means 56.

That is, the blade 18 is connected to the tank truck only with the help of traction means 38, which serve to raise and lower the blade 18, and with the help of traction means 56, which serve to pull the blade 18 by means of the tank truck 10. Moreover, the traction means 38, 56 selected with such a length and arranged so that the blade 18 is held on the tank truck 10, freely oscillating to some extent left and right, that is, in the transverse direction y of the vehicle. Therefore, during movement with the help of the tank truck 10, the blade 18 may deviate left and right with respect to the tank truck.

9 and 10 you can see the expanded operating position of the sections 30, 32 of the blade 18. From these images, you can also clearly see that in the expanded working position these two sections 30, 32 protrude behind the tank truck 10 in the transverse direction y. Further, when comparing the two views in FIGS. 3 and 10, it is clearly seen that the blade 18, when located in FIG. 10, is lowered in the direction of the soil noticeably further than when located in FIG. 3.

In accordance with the figures in FIGS. 8, 10 and 11, the suction inlet 20 has been lowered relative to the blade 18 even so that its open end is located below the blade 18. Although this, in principle, is possible, but usually is not the normal position of the suction inlet 20 in relation to the blade 18.

Instead, it is preferably provided that the suction inlet 20 is rearranged, respectively, rearranged relative to the blade 18 in the vertical direction z so that the suction inlet 20 does not touch the ground, while the blade 18 in its deflated working position moves along the soil 18 to collect and rake the liquid slurry that is being taken.
